(IBM-FO-017) Section 14.1.1, fn:name: Fifth paragraph says that "the value
returned is an xs:string whose lexical form is an xs:QName." But it does
not tell us where this string comes from. Elsewhere, the F&O document
tells us that there is no way to cast a QName into a string. This is an
inconsistency in the document.
